Observation and assessment of  international activities in research and development 
by means of  frequency analyses of the world-greatest bibliographic databases

 

2  Bibliographic online databases as a reflection of the worldwide activities
in research and development

To the table of contents
 
The results of R & D activities appear in scientific publications. These are journal articles, research reports, conference papers, university publications, textbooks, patent documents and other information sources in printed form or on electronic data carriers.

The publication is the printed reflection of the work of a scientist. The quantity of publications of a group of researchers and developers which is definable in terms of  research subject, time and place reflects the activities of the group.

Each one of change of this image, recognizable in the frequency distributions of the publications, is in the rule the result of changes in the R&D-processes that  take place  in front of the publications.
The frequency distributions therefore permit to draw conclusions about the course of the relevant research and development processes.
Draw of such conclusions is possible under several aspects:
- with reference to themes, i.e. fields, orientations or topics of R&D;
- with reference to time, i.e. defined periods of  time;
- with reference to location, i.e. institutions, countries or country-groups.

Of great importance are cognitions about formation of  thematic and territorial nodal points in research and development. Also significant  are informations about ending or breaking off existing works or about setting new targets for such works (table 3).

For the recognizing of frequency distributions the scientometric analysis of bibliographic online databases containing the various publications is a powerful instrument.
By means of this instrument it is possible to obtain condensed information about worldwide publication activities of the last years and of the present time. 
It also allows short-term-forecasts of the expected main trends  in publication activities  of the nearest future.

 
Bibliographic online databases for special subject areas already have been compiled since the 1960s years. These databases contain the records of the scientific publications of the whole world. 
That means many millions of bibliographic records in the largest among them. 
The rates of increase of these databases are considerable and relatively stable. (table 1)

The totality of bibliographic online databases (including above files) gives a realistic image of the research and development activities in the whole world as well as with reference to separate countries or to groups of countries.
